FRANCIS L. MITOHELL, OF DALLAS, TEXAS.

GAS-GENERATING MACHINE.

SPECIFICATION for-ming part of Letters Patent No. 578,347, dated March9, 1897.

Application filed April 4, 1896. Serial No. 586,242. (No model.)

To aZZ whom, it may concern:

Be it known that I, FRANCIS L. MITCHELL, a citizen of the United States,and a resident of Dallas, in the county of Dallas and State of Texas,have invented certain new and useful Improvements in- Gas- GeneratingMachines; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawing, and to letters of reference marked thereon,which forms a part of this specification.

The figure of the drawing is a representation of the apparatus and is aside elevation, partly in section.

This invention is designed to provide an improved method of and meansfor generating hydrocarbon vapors for heating and lighting purposes; andit consists in the novel manner in which the process is carried out andin the novel construction and combination of parts comprising thegenerating apparatus, all substantially as hereinafter described, andpointed out in the appended claims.

Referring to the accompanying drawing, the letter A designates a largetank or reservoir into which air is forced under pressure by a suitablepump, such as indicated at B. This pump is shown as being of doublerotary character with intergeared pistons B, but any other suitable pumpmaybe employed.

0 is the pipe which connects the exhaust of the pump with the said tankor reservoir A.

D designates a retort which is supported horizontally adjacent to thetank A and which is designed to be filled or partly filled with ahydrocarbon fluid, such as coal-oil, gasolene, camphene, or benzin, orwith a suitable mixture of two or more of these fluids. Inside of thisretort is a transverse oblique partitionwall D, which extends from theupper forward end of the tank to a point near its lower rear end and isperforated at its lower portion, as indicated.

E is a pipe which connects the upper portion of the tank A with thelower portion of the retort D, into which it extends for some distanceunderneath the wall D.

d is a normally-closed filling-opening for the retort D.

F designates a generating retort and reservoir whose lower portion isconnected with the upper forward portion of the retort D by means of apipe G. Said pipe extends into the reservoir F and terminates in therose G.

H II designate perforated horizontal straining and disseminatingdiaphraglns or partitions located one above the other in said reservoirF.

I designates a pipe which leads from the upper portion of said reservoirback underneath the retort D, where it is provided with burner orburners I. This forms a convenientmanner of heating said retort, but itmay, however, be heated in any other suitable manner.

J is a normally-closed filling-opening for reservoir F.

K indicates a service-pipewhich may lead to any point where the vapor isto be burned. The said reservoir F isdesigned to be partially filledwith gasolene or some other hydrocarbon fluid.

The operationis as follows: Air under pressure passes from thereservoirA to the retort D, and, escaping from the pipe E, it is forcedthrough the heated hydrocarbon to the pipe G and thence to the reservoirE. On account of the extension of the pipe E into the retort F and theprovision of the partition-wal1 D above such extension it will beobserved that the air is pretty thoroughly disseminated throughout theheated hydrocarbon, so that before passing to the reservoir Fit is to alarge degree impregnated with the heated vapor thereof. As theimpregnated air escapes into the reservoir F it undergoes a secondimpregnation, being disseminated and strained by the perforatedpartitions II. The resultant Vapor, which accumulates under the pressureof the upper portion of this reservoir, is of a superior quality and ofgreat efficiency for-heating and lighting purposes. The several pipesare provided with necessary valves.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In apparatus for generating hydrocarbon vapors, the combination withan air-reservoir,

of the retort D, having therein a single transverse, oblique partitionwall D, extending from the upper forward end thereof to a point near thelower rear end, and perforated for a portion of its length, a pipeextending from the air-reservoir into said retort and to a pointunderneath the upper end portion of said partition-wall, a second retortand reservoir, a pipe connecting the same with the upper forward portionof the retort D, and means for heating said retort D, substantially asspeci fied.

2. Apparatus for generating hydrocarbon Vapors comprising anair-reservoir, a forcepump for supplying the same, a heating-retortconnected to said reservoir, and having therein an inclineddeflecting-partition perforated for a portion of its length and dividingthe retort into upper and lower chambers having communication with eachother at one end of said partition, and also through the FRANCIS L.MITCHELL.
